math: Decompose math-use-builtins.h

Each symbol definitions are moved on a separated file and it
cover all symbol type definitions (float, double, long double,
and float128).

It allows to set support for architectures without the boiler
place of copying default values.

Checked with a build on the affected ABIs.
